Definitions

  • the invention is directed to a fluidized bed reactor for oxychlorination of ethylene, oxygen and HCl with one heat exchanger consisting of several tube packs in the fluidized bed to release the due to exothermic reactions heat generated on a heat transfer medium in the tube packs, especially water / steam, with the tube packs supplied with water via a ring line and the steam is removed via a ring line.
  • Oxychlorination uses ethylene, oxygen and HCl in a fluidized bed reactor (oxi reactor) on a copper Catalyst converted to 1,2-dichloroethane and water.
  • the heat generated in this implementation is from the catalyst via a pipe system located in the reactor (consisting of several pipe packages) on Boiler Feed Water given off for steam generation or a heat transfer medium.
  • the BFW (the heat transfer medium) is replaced by an outside of the reactor horizontal ring line distributed over the pipe system.
  • the steam produced (the heated heat transfer medium) is over a ring line also located outside the reactor collected and discharged.
  • the two outer ring lines have depending on the number of the tube packs in the inner tube system Variety of connecting lines through the jacket to the Pipe packages.
  • Perforated disks are used to determine the pressure drop to achieve an even distribution on the individual tube packages. Accessibility and maintenance of the ring lines is reached via a 360 ° stage.
  • An illustration of the Ring lines as a model for pipe tension calculations is very complex and expensive.
  • the Oxi reactor must be very be carefully insulated to avoid falling below dew point avoid. Due to the many shrouds for the ring line connections and the stage consoles is difficult and time consuming.
  • the object of the invention is to provide a solution with one avoiding the disadvantages described above compact, easy to manufacture but inexpensive solution is created, the elaborate drill bushings avoids, especially the calculation of ring lines relieved and a variety of jacket penetrations makes dispensable.
  • the invention makes it possible to pass through the large number of sheaths or the perforated disks through simple holes to be replaced in the internal collector so that the Isolation of the reactor is greatly simplified.
  • a special configuration for example, consists in that the holes for connecting the pipes to the definition a desired pressure loss and thus to equalize the pressures of the different Pipe packages are listed as throttle bores.
  • the reactor generally designated 1
  • points here a variety of tube packs 2 with as a heat exchanger arranged on a console 3 outside the reactor jacket 4 Ring lines 5 and 6 for example for the incoming Cooling water in the ring line 5 and the withdrawn Steam in the ring line 6 Drain lines 7 and 8 individually through the reactor jacket and the associated arithmetic, constructional and manufacturing expenditure.
  • the Pipe bundle 2 is a simplified representation of the same type Section through the corresponding part of the invention Reactor, also designated 1, shown.
  • the Pipe bundle 2 ends here in two attached to the inside of the wall, for example rectangular or trapezoidal Ring collectors 9 and 10, with the ring collector or distributor 9 introduced the heat exchange medium and for example the steam is drawn off via the collector 10.
  • the reactor jacket 4 To enforce only in the example shown in FIG. 2 two cross-pieces 11 and 12 the reactor jacket 4.
  • the feed lines 7 or the return lines 8 for the steam only penetrate the inner wall of the collectors 9 and 10.
